Hey, this should be fun.
For my tower bit, my first step is to design a defensive clock tower (go zilean!). I'm far from being a concept artist, however these thumbnails should still communicate what I'm trying to get at. I want it to be strong and defensive near the bottom but a little more elegant and ornate as it gets taller -- as a clock tower may be. all the intricate bits and gears would be higher.
creep den sketches coming later.
